Some suggestions for TFT

So, I've been playing TFT a lot. I came back to League to play it. It's quite relaxing all things considered, even when RNG spites you lol. Either way I wanted to add a couple suggestions. I was going to suggest more items, but it looks like Riot has already considered this and is making a patch. However, I really want to see more champions available. Something I run into over and over again is the same types of champion combos. I would like a little more diversity in the gameplay. Maybe add Ionians? That'd be an interesting combo to work with. My only other suggestion is that I would like there a way to be able to get a little legend without having to pay a ton of money for one. Perhaps we can have an event where we can earn it with gameplay and missions? I know I'm just throwing out questions and suggestions and some of them may have already been made, but I wanted to add my own suggestions because I do enjoy the game mode. And I certainly hope that the upcoming game is still on the way.
